Operation assessment for newly built chemical plants
Thread Content
Let’s all discuss why the assessment for chemical processing units requires 72 hours of continuous stable operation Is there a clear written rule? Can all newly developed devices be scaled up or put into industrial production once they have passed the 72-hour calibration and testing? For some new process technologies, especially large-scale coal chemical and petrochemical projects, isn’t a 72-hour operation test too short a period of time? How can it be ensured that there will be no problems during long-term operation, particularly after scaling up?
The main things to check are whether the equipment is operating properly, whether the process flow is unobstructed, and whether all indicators are within normal ranges; 72 hours of continuous operation is generally sufficient
Performance testing is independent of the size of the device, and project acceptance requires performance testing.
The operation assessment time varies for different devices; for example, it is 168 hours for power plants
Each set of equipment corresponds to a specific performance evaluation plan; equipment that has been scaled up for industrial use still needs to undergo further testing, so it’s not possible to make generalizations. As for the duration of the testing, 72 hours (under full load operation) is the usual timeframe. The poster can also refer to the \"HG 20231-2014 Specifications for Commissioning of Chemical Industry Construction Projects.\"
72 hours is a *practice; if there are other provisions in the trial run contract, those should take precedence. Moreover, the tracing of quality incidents caused by substandard materials does not depend on any conditions, whether it is during the trial period or the warranty period.
7×24, I guess; 72 hours is a bit short
Things that are customary – everyone does them; there’s no need to worry about such things! ! ! ! ! ! ! ! ! ! ! !
